Maintenance and Calibration Tips for ATEX Weighing Scales

Working in hazardous environments demands the highest standards of safety and accuracy, and your ATEX weighing scales are no exception. These machines play a crucial role in ensuring precise measurements while minimising the risk of explosions in potentially hazardous atmospheres. But their specialised nature requires equally specialised care. This blog post outlines essential maintenance and calibration tips to keep your ATEX weighing scales performing optimally and safely.

Why is Maintenance and Calibration so Crucial for ATEX Scales?

ATEX (Atmosphères Explosibles) equipment is designed to operate safely in environments where flammable gases, vapours, mists, or dust may be present. Any malfunction or inaccuracy in weighing can have significant consequences, from production errors to potentially dangerous situations. Regular maintenance and calibration are therefore paramount for:

  • Safety: Ensuring the scale’s intrinsic safety features remain intact and functional, preventing ignition sources in hazardous areas.
  • Accuracy: Maintaining the scale’s precision for reliable measurements, crucial for quality control, material management, and regulatory compliance.
  • Compliance: Adhering to ATEX directives and other relevant regulations, avoiding penalties and ensuring a safe working environment.
  • Longevity: Extending the lifespan of your valuable weighing equipment through preventative maintenance.

Maintenance Best Practices for ATEX Weighing Scales

Regular Inspections

Implement a schedule for routine visual inspections. Check for any signs of damage, wear, or loose connections. Pay close attention to cables, seals, and grounding connections. Look for any build-up of dust or debris that could affect performance or create a hazard.

Cleaning

Clean your ATEX scales regularly, following the manufacturer’s guidelines. Use appropriate cleaning agents that are compatible with the hazardous environment and the scale’s materials. Avoid harsh chemicals that could damage the scale or its protective coatings. Remember to disconnect the scale from the power source (if applicable and safe to do so) before cleaning.

Professional Servicing

Schedule regular servicing by qualified technicians trained in ATEX equipment. These professionals have the expertise to identify potential issues and perform necessary repairs or replacements.

Documentation

Maintain meticulous records of all maintenance and calibration activities. This documentation is essential for audits and demonstrates your commitment to safety and compliance.

Environmental Considerations

Be aware of the specific environmental conditions in your workplace. Extreme temperatures, humidity, or corrosive substances can impact the scale’s performance and require more frequent maintenance.

Calibration Essentials for ATEX Weighing Scales

  1. Frequency: The frequency of calibration depends on the scale’s usage, the criticality of the measurements, and regulatory requirements. Consult the manufacturer’s recommendations and relevant standards for guidance. In high-risk applications, more frequent calibration may be necessary.
  2. Certified Calibration: Calibration should be performed by accredited laboratories such or certified technicians with expertise in ATEX weighing equipment. This ensures the calibration process is traceable and meets the required standards.
  3. Calibration Procedures: Follow established calibration procedures, using certified weights and appropriate equipment. The process may involve adjusting the scale’s settings to ensure accurate readings across its weighing range.
  4. Verification: After calibration, verify the scale’s accuracy by performing test weighings with known weights. Document the results of the verification process.
  5. Software Calibration: Many modern ATEX scales incorporate software for calibration. Ensure that the software is up-to-date and that the calibration process is performed correctly.

Key Considerations for ATEX Environments

  • Intrinsic Safety: Understand the specific intrinsic safety rating of your scale and ensure that all maintenance and calibration procedures adhere to these requirements.
  • Grounding: Proper grounding is crucial for preventing static electricity build-up, which can be a significant ignition source in hazardous atmospheres.
  • Spare Parts: Use only genuine, certified spare parts when replacing components in ATEX weighing scales. Using non-approved parts can compromise the scale’s safety and performance.
  • Training: Ensure that all personnel involved in the operation, maintenance, and calibration of ATEX weighing scales receive adequate training on the specific requirements for working in hazardous environments.

By following these maintenance and calibration tips, you can ensure the safety, accuracy, and longevity of your ATEX weighing scales, contributing to a more efficient and secure working environment. Don’t compromise on safety – prioritise regular maintenance and calibration for your weighing equipment with ATEX specialists like MWS. It’s an investment that pays off in the long run.
